Much more realistic review :D
PvP is where the game really starts and well worth the grind. When your a lowbie you'll get killed maybe a dozen to two dozen times as you try to reach lvl40. But once at lvl40+ you can easily kill 50+ or 100+ if you know what your doing or go with your friends to pvp. There is a chipwar which, in theory, you can participate and do some damage to the other race at lvl25. But now with soo many lvl50s you'll want to be lvl45+ to enter unless you want to spend the whole CW debuffing people which I dont think is very fun. It is also easy to start your own mini wars against other races, just raid their areas with a group and if your lucky they'll respond with their own group of people. Also half the time you'll find that the chance to pvp will come to you when a opposing race member tries to attack you.
There is a lot more then just killing stuff though. You can get guilds which give you company while grinding, help you grind and you can pvp with them. There are PBs to kill which give really good equipment. Battle dungeons which give Leon piecies which you then combine to get a Leon weapon. Dark holes which give you relic weapons (which look kickass). The scary task of upgrading weapons but there is a huge variety of upgrades and combination available. And also just getting new equipment is really worth grinding for or farming for.
All sumed up, this game is amazing! download now! its free and you'll be able to go to space with the next big update!
